Canon  50mm F1.2  M39 Screw Mount Lens with caps . Optics are decent with light dust specs and I can see some wipe marks plus fogging and haze inside which must be cleaned to make use of this lens, aperture work fine but oil on blades and focus works fine.Overall in a decent shape with some  wear.Selling As is.

again lens shows haze and fog inside which needs pro cleaning.

As is!
